NetSurf redraws its pages in rectangular sections. This process

At the moment, if an error occurs (e.g. JPEG data is invalid or
otherwise fails to decode), the redraw of the entire section is
cancelled. This is undesirable, because it leads to the appearance of
large blank white spaces on a page with invalid images on it.
You can see an example of the problems this causes here:
http://www.corporateskull.com/
There are two invalid JPEGs in the sidebar there (or at least JPEGs
which RISC OS doesn't seem to like; Linux renders them OK). These are
the link to 'Skull Art' just beneath the (working) 'Corporate Skull
Guest Artist Week' image, and the Ink Outbreak avatar in the top-left of
the box beneath that.
If you slowly scroll down the page using NetSurf on RISC OS, you'll see
a thick white horizontal bar blotting out the image in the blog post to
the left of the Skull Art picture, as well as the Skull Art picture
itself failing to render.
If you press F12 and then Return with the faulty JPEG showing, most of
the window goes white!
NetSurf may not be able to render an image, but could it at least not
trash the rest of the page because of it?
Sounds as if this might be a manifestation of bug #3435099
